This game uses a launcher. For ease of use I recommend permanently altering the standard gamepad controls in order to allow mouse control on one of the track pads or with the gyro and mouse clicking. Alternatively you can hold steam button and use the trackpad as mouse at all times steam button plus right trigger is mouse click and steam button Plus right on the d-pad is enter. As a tertiary option, you can navigate the launcher and alter settings exclusively through the touchpad.
The game works flawlessly with graphic settings maxed and at native resolution for the steam deck with a flawless 60 frames per second at all times with literally zero stutters. The only consideration is controls and that's only because graphic settings and some other things like that are configured in a launcher window that only works with mouse input, not gamepad input. But if you've played around with the steam deck or the steam controller or really any kind of steam input any reasonable amount you should be well versed in these kinds of minor hiccups and how easy they are to bypass or work around. Overall the experience with this game is essentially flawless.

Installed from Amazon Prime Gaming
Installed from Amazon through Lutris. Black screen or freeze on splash screen depending on wine/proton version. Targeted GSGameExe_DX9.exe and added as non Steam game. Forced Proton experimental. Added cd "${STEAM_COMPAT_INSTALL_PATH}/launcher"; gamemoderun %command% to launch options. Runs great through first levels so far. Solid 60 fps and no hiccups. Will update if any change or on completion.
Had to use Steam + Trackpad and Steam + R2 to navigate the launcher and configure the settings.

Use of touchscreen/mouse is required in the initial launcher if you want to change settings. You can use the shortcuts without having to edit the layout to get past the launcher
- Steam + R Stick for mouse
- Steam + R Dpad for Enter (Play)
Use shortcuts to get past the launcher.
Graphic settings are outside of the game. By default, the trackpads don't function as a mouse and will require using the touch screen to adjust. Works great at 60 fps.
